I thought about the 5amp but I sometimes do mega roast sessions with zero
roaster rest. (Christmas gifts etc.) Just dump, reload and start the next
batch. The review over at Coff#$%^&*()+ said when they did as I do the plug
socket melted so figured I'd best not risk it. For a couple batches in a row
fine, but not more than 20 back to back batches in 6 to 8 hours non-stop!
BTW, are you over fusing to 15amp as the site suggested?

I generally do six roasts in a row. But 6 to 8 hour marathons? Forget about a 
20 amp variac, what you need is a San Franciscan!
But seriously, mine never warms up, or changes it's hum tone from no load to 
load. It's supplied with a 15 amp fuse. 
I'm not an EE, but wouldn't a fused plug indicate a bad fit in the plug, rather 
than an overload in the transformer? As a kid, I once overloaded a model train 
variac; it looked real pretty as a bright blue light worked its way around the 
windings - then the lights went out for the whole block.  Anyhow, nothing like 
that with the 5 amp.
Whichever one you get, you'll be pleased -- tanks are built like these KRMs.

My usual is 4 to 8 batches at a time. Yeah, my Christmas session was INSANE!
I roasted 1# for 7 people in one session.(1/2# of two diff' for each, love
those gold foil bags Tom sells...) 1/4# finished roast each batch, 28
batches! I'll definitely be picking up another roaster before this years
Christmas roasting, either another Rosto or I may take the plunge and go for
the HotTop. A 1# plus roaster would be, well, way expensive!  (I've
looked at the San Franciscan and others, in my dreams...)

Just an FYI, the 15amp fused is supplied by the re-seller, not the Variac
manufacturer. What would happen liability wise if say a 12amp load caused
the Variac to catch fire and burn down your house? It was sold to you with a
15amp fuse, not the manufacturer rated 5amp. I wonder if they've checked
with their legal beagles on their potential liability. Plugs have current
ratings too. The current flowing throw the plug generates heat. Heat melts
stuff. Same current through smaller wire or plug generates more heat than
larger wire or plug. The 5amp Variac's plug may or not be rated for 15amp.
The unit itself is not.
Of course, I'm nuts too and if I get two Rosto's will play with running them
simultaneously off the 20amp Variac!  The thought is to only have one in
roast mode at a time, the other in the cooling fan only stage... though this
should not exceed the 20amp rating. Both roasting would...

KRMs.
Ordered the 20amp earlier today, can't wait for new another Toy!
